Dashcode’s integrated environment allows you to lay out, code, and even test widgets and web applications without opening any other applications. Its layout tools, composers, and editors simplify the process of creating all the resources these projects need. Dashcode also includes handy coding and debugging tools that help you manage and test the code you write.
